Aggregates
· Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydrauliccement concrete, or iron blastfurnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the mm (No. 4) sieve, are called coarse aggregates. Those particles passing the mm (3/8 inch)
